What happens when an oil drop is driven toward a solid surface into a water bath ? This phenomenon, common in the oil industry, is poorly understood. A team at PIC (joint laboratory between SIMM and TOTAL) evidenced three successive regimes for that collision: a purely hydrodynamics regime followed by two regimes controlled by both the hydrodynamics and the long-range interactions across the water film squeezed between oil and solid.
In a recently published paper, we report on a theoretical and experimental investigation of the normal contact of stretched neo-Hookean substrates (…)
In the frame of PIC lab (Laboratoire Commun Total/ESPCI/CNRS/Sorbonne Université) SIMM researchers explain for the first time a long-known effect: (…)
